Laboratory Consumables Supplier

Precision Consumables Manufactured for Reproducible Laboratory Work

Shanghai Qiujing Biochemical Reagent & Instrument Co., Ltd. manufactures laboratory consumables alongside precision pipettes and bench instruments. Our brand has been in the laboratory sector since 1988, our Chinese and English trademarks were registered in 1992, and the company now operates a 24,000 m² production site in Songjiang District, Shanghai, with CE and ISO 13485 quality system certification.

As a China Laboratory Consumables Supplier, we serve distributors, research institutes, hospital laboratories, and industrial quality-control departments that need disposables matched to a defined sample workflow rather than a single catalogue item. Consumables are produced with high-precision abrasives under strict process control, and the range is designed to be odour-free, smooth, and transparent where optical clarity matters.

The Laboratory Consumables Range We Supply

Our consumables line covers eleven items across counting, centrifugation, filtration, culture, and liquid-handling support. Each family is produced for a specific position in the workflow, so the physical format, ruling style, or membrane chemistry is chosen against the protocol rather than the shelf.

Application Fit Across Sample Workflows

Consumables are selected against the sample matrix and the read-out that follows. Counting chamber slides sit at the microscopy step, where ruling visibility decides how quickly an operator can reach a repeatable count; our dark-line slide keeps its separator lines clear after repeated rinsing, which supports daily counting routines and long working sessions.

Centrifuge tubes sit between collection and separation. The USP-6 PP high-transparency tube is used for bacterial, cellular, and protein samples where the inner wall finish affects recovery, while the USP87 ultrafiltration format is specified where retention accuracy and low protein adsorption drive the result. Downstream, the single-use gamma pre-sterilised vacuum filter device covers media and solution sterilisation, and the organic syringe filter with hydrophilic or hydrophobic membrane covers clarification of aggressive solvents.

• Life science and cell work: counting slides, high-transparency centrifuge tubes, petri dishes, low-retention tips.
• Biotechnology and pharmaceutical QC: ultrafiltration tubes, pre-sterilised vacuum filtration, pyrogen-free tips.
• Food, environmental, and industrial testing: syringe filters for sample clarification, centrifuge tubes for pre-treatment.
• Teaching and research laboratories: bench consumables and pipette stands for organised, shared working positions.

Materials, Cleanliness, and Critical Specifications

Polypropylene, polystyrene, and membrane assemblies are selected per application. Optical transparency governs slides, dishes, and tubes used with transmitted light; surface energy governs filters and tips where residual liquid is measured. Consumable products in our range are produced with high-precision abrasives and controlled process conditions so that moulding marks, odour, and wall irregularities do not interfere with observation.

Specifications we confirm before production include material grade, ruling type and line contrast, groove geometry, membrane chemistry and pore size, sterilisation state, racking or bagging format, and the packing unit used for storage and transport.

Consumables in an Instrument-Led Workflow

Consumables only perform when they fit the instruments around them. Our pipetting range includes single-channel micropipettes, macropipettes, and the automatic micro liquid dispenser, and our low-retention pipette tips are matched to the tip cone of the pipette in use so that fit, sealing, and ejection remain consistent across a full working day.

For laboratories assembling a complete bench, our laboratory instruments range covers centrifuges, magnetic stirrers, mixers, water baths, metal baths, balances, photometers, and pH meters. We confirm the tube format against the rotor, the dish format against the incubator or microscope stage, and the filter connection against the syringe or vacuum manifold at the quotation stage, not after delivery.

OEM/ODM Configuration, Packaging, and Delivery Scope

We support OEM and ODM programmes based on customer drawings or samples, covering product design, specification adjustment, appearance customisation, and packaging solutions. Consumable projects typically involve mould or tooling review, a sample round for performance verification, and a documented specification freeze before formal production.

• Configuration inputs: volume or dimension, material grade, ruling or membrane type, sterility requirement.
• Presentation: bagged or racked, bulk carton or partitioned tray, private-label printing.
• Delivery scope: export packing, carton labelling, and documentation prepared for the destination market.
• Standard lead time: 10 working days, confirmed against order quantity and customisation depth.

Quality Control and Acceptance Evidence

Raw material inspection, in-process testing, and finished-product inspection run as separate gates under our quality management system, which is certified to ISO 13485 and supported by CE documentation and an in-house test laboratory. Certificate records held by the company include the EU Medical Device Notification certificate, the Certificate of Export Sales for Medical Devices, and the Class I Medical Device Production Record Certificate.

Acceptance of a consumable batch is normally agreed on the specification sheet: material, dimensions, ruling contrast, sterility and pyrogen state, inner-wall finish, and packing count. Where a customer protocol requires incoming inspection, we align the sample set and the inspection list before the first production run so that both sides measure the same characteristics.

Information We Use to Configure Your Solution

Our sales and technical team works from the application first. The following inputs let us return a specific configuration, sample plan, and quotation rather than a generic price list.

1. Application and sample type: cells, protein, blood-derived material, solvent, food or environmental extract.
2. Working parameters: volume range, count format, centrifugation speed and rotor, filtration volume and membrane choice.
3. Instrument or interface details: pipette model, rotor bore, syringe fitting, incubator or microscope stage dimensions.
4. Cleanliness requirements: pyrogen-free, DNase/RNase free, sterilised, or standard laboratory grade.
5. Presentation: bagged, racked, bulk, private label, and the unit count per carton.
6. Order profile: first-order quantity, repeat schedule, OEM/ODM scope, and destination market documentation.

Storage, Handling, and Technical Support

Consumables are supplied in sealed, clearly labelled packaging intended for dry, room-temperature storage away from direct sunlight and solvent vapour. Batch and product numbers are printed on the outer pack so that a result can be traced back to its production run, and racked formats are designed for direct loading onto the bench without repacking.

Our technical team supports product consultation, operation guidance, and troubleshooting after delivery, and can revisit a specification if a protocol changes. Keep a record of the product number and model for each consumable line — for example XB-K-25, XB-K-25Plus, or XB-K-25Pro for counting chamber slides — and include it in any follow-up request so that we can match the correct format.

Frequently Asked Questions

Which cell counting chamber slide should I choose?

Choose by how you read the grid. The dark-line slide XB-K-25Pro gives high contrast for routine counting and repeated rinsing; the metal silver bottom bright-line slide XB-K-25Plus suits bright-line counting with a polished, specially processed surface; the H-shaped groove slide XB-K-25 provides a smooth cell-counting channel with clear scale lines. The full set sits in our Laboratory Consumables Supplier range.

How do you handle centrifuge tube selection?

We match the tube to the sample and the rotor. USP-6 PP high-transparency tubes with a smooth inner wall are used for biological sample collection and standard centrifugation, while USP87 ultrafiltration tubes are specified where retention accuracy and low protein adsorption determine recovery. Rotor bore and speed rating are confirmed before quotation.

Are the pipette tips free of pyrogen and nuclease contamination?

Our tips are produced to ensure no heat source, no endotoxin, no DNase, and no RNase, with a smooth inner wall and an optimised aperture for consistent liquid release. They are supplied bagged or racked, with clear and low-retention options.

Can you supply consumables under our own brand and packaging?

Yes. We run OEM and ODM projects covering product design, specification adjustment, appearance customisation, and packaging solutions, based on your drawings or samples. Samples are provided for performance verification before a specification is frozen for production.

What quality documentation accompanies a consumables order?

Our quality management system is certified to ISO 13485 with CE documentation, and we hold the EU Medical Device Notification certificate, the Certificate of Export Sales for Medical Devices, and the Class I Medical Device Production Record Certificate. Batch records and inspection results are prepared against the agreed specification sheet.

What is the typical lead time and how do I start?

Standard lead time is 10 working days, confirmed after order details and any customisation scope are agreed.
